Teachers Attitudes

Kindergarten teachers' attitudes toward immigrant children and children of immigrant families is the subject of research conducted between 2009 and 2010. The study compares teachers in the public schools of Avignon, France, with state school teachers of Reggio Emilia, Italy. The analysis conducted mainly considered relations between two variables. However, the research tools used (participant observation, Likert type-scale questionnaire and semi-structured interviews) also allowed for the triangulation of data. The intent of this article is to elaborate on the methodological contribution to the research using multivariate analysis. This analysis provides both three-dimensional representations of the teachers' attitudes as well as individualized representations of relevant relations between variables. The statistic test of the null hypotheses, the "chi-square test" is used. The analysis points out attitude and behaviour differences between Reggio Emilia teachers and Avignon teachers. Differences are mostly observed in the synchronic dimension data analysis. Nevertheless, if the point of observation is changed and data are studied in the diachronic dimension, that general view demonstrates how a current historical period influences educational choices within a particular educational system and consequently influences teachers' attitudes.

 Objective. To estimate the prevalence of Metabolic Syndrome (MS), its components and its association with obesity and cardiovascular risk in school age children. Materials and methods. A cross-sectional study of 1,017 children from 6 to 12 years of age. Anthropometric information, blood pressure, glucose, insulin, cholesterol, HDLc, LDLc and triglycerides were collected. The presence of MS and its components were determined by criteria of Cook et. al. (2003), modified for children and adolescents. In the analysis, the children were grouped by aged group of 6 to 9 and 10 to 12 years. The association between MS, obesity and cardiovascular risk was estimated using Student’s t-test and Mann-Whitney U test, Chi-square test and logistic regression. Results. The MS was present with 54.6% in obese children. Obesity was the characteristic of greater association to suffer from MS with an OR=8.62 p<0.001. Conclusions. MS is high among children with obesity, and is mostly associated with insulin resistance and atherogenic risk.

Knowledge And Attitude

Smoking is one of the health risk behaviors that increasingly threatens young and even teenagers. Not only in public schools, but also the increasing number of Islamic boarding schools. Even in some Islamic boarding school activities, in addition to serving food, the boarding school also provides treats for cigarettes. This is a challenge that is still difficult to resolve, because the age of smokers is getting younger. This study aims to find out the relationship between knowledge and attitude with smoking behavior of students in Surabaya Al Jihad Islamic Boarding School. Method: This study was an analytic observational study with crossectional design. The population of this research is all students who live in Al Jihad Islamic Boarding School Surabaya. The study sample was 97 respondents who were selected by random sampling. Data collection is done by interviewing using a questionnaire. Data were analyzed using the chi square test. This study shows that there is no significant relationship between knowledge (p = 0.885) and santriwan smoking behavior. But there is a significant relationship between attitudes and santriwan smoking behavior (p = 0.025). Strengthening the knowledge and attitudes of santrians regarding smoking is important, because this can affect the smoking behavior of santri in Islamic boarding schools. It is expected that the leaders and managers of Islamic Boarding Schools are committed to implementing a non-smoking area by providing warning bans on smoking around Islamic boarding schools

Aims: The aim of the study was to assess menstrual hygiene practices and examine access to sanitary materials and facilities and how they influence effective menstrual practices and management among girls in Kibera slum Kenya. To achieve this cross-sectional study was conducted in mixed day secondary schools. Methodology: A cross – sectional study design was adopted. Simple random was used to select 25% of public schools and 25% of private schools with a population of 1778 girls. Fisher’s sample size formula was used to select 384 respondents.  The study was conducted in Kibera slums, Nairobi Kenya. Data on factors influencing effective menstrual practices and management among girls in Kibera slum was obtained through interviewer administered questionnaires. Chi-square test of independence, Pearson’s correlation analysis and multiple regression analysis were used using IBM® SPSS® Statistics 20. Results: Menstrual management amongst the 355 secondary going girls in Kibera slums with a median age of 16 years was influenced by menstrual hygiene practices and access to sanitary materials and facilities. These two factors accounted for up to 75.3% as indicated in the regression model. Of the two factors access to sanitary facilities and materials had the greatest influence on menstrual management (β = 0.842 p < 0.05) while menstrual hygiene practices had the least effect (β = 0.089 p < 0.05). Conclusion: Our study identified that menstrual hygiene practices and access to sanitary materials influenced effective menstrual practices and management among girls in Kibera.

Low Performance

Hospital is a health service with excellent and competitive service demands by its users. The function of the hospital was developed by the guidance of science and technology at its time. Performance appraisal is the most reliable tool for managers to control human resources and productivity and can be used effectively to direct employee behavior to produce nursing services based on high quality and quantity. The purpose of this study was to analyze the factors causing the low performance of nurses in Medan city hospital. This type of research is a quantitative study with a cross-sectional study design. This research was conducted at the Royal Prima Medan Hospital in July. The sample in this study were all nurses who served in the inpatient room. The sampling technique in this study using saturated sampling techniques totaling 159 nurses. Data collection using a questionnaire with the chi-square test. The results showed that the three-dimensional factors of nurse performance had a relationship with the performance of nurses, namely individual factors p = 0.000, psychological factors p = 0.006, and organization p = 0.002. This research concludes that the majority of nurses in the hospital still have low performance. The researcher's suggestion for the hospital is that the hospital pays more attention to the performance of the nurses who work in the inpatient room.

A recent book by David Newbold (1977) on the Banbury Enquiry into Ability Grouping contains an analysis of children's choice of friends. The variables concerned are sex, mixed ability/streamed classes, and closeness of ability of the friendship pairs as measured by a verbal reasoning test at the end of the first year of secondary schooling. The method of analysis was such that all three variables were dichotomous. This article re-analyses Newbold's data by using a little known development of the chi-square test and suggests that this technique deserves to be more widely known in educational research.

SUMMARY OBJECTIVE The purpose of this study is to evaluate the efficacy of the combination of gynecologic imaging reporting and data system (GI-RADS) ultrasonographic stratification and three-dimensional contrast-enhanced ultrasonography (3D-CEUS) in order to distinguish malignant from benign ovarian masses. METHODS In this study, 102 patients with ovarian masses were examined by both two-dimensional ultrasound(2D-US) and 3D-CEUS. Sonographic features of ovarian masses obtained from 3D-CEUS were analyzed and compared with 2D-US. All patients with ovarian masses were confirmed by operational pathology or long-term follow-up results. RESULTS (1)The Chi-square test and multiple Logistic regression analysis confirmed that there were only eight independent predictors of malignant masses, including thick septa (≥3mm), thick papillary projections(≥7mm), solid areas, presence of ascites, central vascularization, contrast enhancement, distribution of contrast agent, and vascular characteristics of the solid part and their odds ratios which were 5.52, 5.39, 4.94, 4.34, 5.92, 7.44, 6.09, and 7.67, respectively (P<0.05). (2)These eight signs were used to combine the GI-RADS with 3D-CEUS scoring system in which the corresponding value of the area under the curve (AUC) was 0.969, which was superior to using GI-RADS lonely (Z-value=1.64, P<0.025). Using 4 points as the cut-off, the scoring system showed the performance was clearly better than using GI-RADS alone (P<0.05). (3) The Kappa value was 0.872 for two different clinicians with equal experience. CONCLUSIONS The combination of GI-RADS and 3D-CEUS scoring system would be a more effective method to distinguish malignant from benign ovarian masses.

The Cost

Three-dimensional (3D) reconstruction using RGB-D camera with simultaneous color image and depth information is attractive as it can significantly reduce the cost of equipment and time for data collection. Point feature is commonly used for aligning two RGB-D frames. Due to lacking reliable point features, RGB-D simultaneous localization and mapping (SLAM) is easy to fail in low textured scenes. To overcome the problem, this paper proposes a robust RGB-D SLAM system fusing both points and lines, because lines can provide robust geometry constraints when points are insufficient. To comprehensively fuse line constraints, we combine 2D and 3D line reprojection error with point reprojection error in a novel cost function. To solve the cost function and filter out wrong feature matches, we build a robust pose solver using the Gauss–Newton method and Chi-Square test. To correct the drift of camera poses, we maintain a sliding-window framework to update the keyframe poses and related features. We evaluate the proposed system on both public datasets and real-world experiments. It is demonstrated that it is comparable to or better than state-of-the-art methods in consideration with both accuracy and robustness.

This study aims to investigate the opinions of teachers working at public, private, and International Baccalaureate (IB) Schools on the evaluation practices, the use of assessment tools, the frequency of documenting data, and the feedback frequencies given to both students, and parents. A questionnaire has been used to collect data from 168 teachers. 84 of these teachers were from public schools, 30 from IB, and 54 from private schools.Percentages and frequencies were examined to describe the data, and the chi-square test was conducted for their distribution. There are two main conclusions derived. The first one is that state schools and private schools differ from IB schools in terms of exam-oriented preparation and evaluations when traditional methods are employed. The second one is that IB schools differ from state schools and private schools in terms of documenting the data and reporting of assessment for learning improvement and process-based evaluation. In terms of teachers` opinions, the ones from the IB schools believed there was a difference in terms of having an assessment policy, collaborative planning processes with partners, and experts, taking into consideration the individual differences, and having an inspection mechanism to monitor of the processes.

Human Towers are one of the most representative traditional sporting games in Catalonia, recognized in 2010 as Intangible Cultural Heritage by the United Nations Organization for Education, Science and Culture (UNESCO). The objective of this research was to study the emotional states (well-being, discomfort, and affectivity) elicited by a representative performance of the colla de Castellers de Lleida. This research is based on an ethnographic case study, with mixed methods in which 17 key informants (castellers) voluntarily participated. Participant observation was used; the data were recorded in a field diary and oral sources (semi-structured interviews). The content analysis was done using the Atlas.ti software (version 8.4.4). An SPSS database was also created. The statistical techniques were: Descriptive statistical techniques, cross tables with Pearson's Chi-square values (significance level of p &lt; 0.05). We also used a classification and regression trees (CRT) to examine the predictive capacity of five independent variables (data source, logic, semantic units; contexts of a performance) of emotional states. The results reveal that the comments (n = 132) were mostly oriented toward well-being states (n = 70; 53%), The internal cooperative logic of the Human Towers enhances the intense interpersonal relationships of socio-emotional well-being.
